Integrating China in the International Consortium for Personalized Medicine: A Position Paper on Personalized Medicine in Sustainable Healthcare.

INTRODUCTION: Over the last decade, the emergence and spread of personalized medicine (PM) have defined a substantial revolution in healthcare. In principle, healthcare system sustainability is challenged by the investments required for research and development, as well as the adoption of PM techniques in routine clinical care. The "Integrating China in the International Consortium for Personalized Medicine" (IC2PerMed) EU-funded project aims to integrate China into the "International Consortium for Personalized Medicine" (ICPerMed). IC2PerMed aims to align the EU and China's research agendas in this field to enable a swift development of approaches in the EU and China with strong leverage upon EU-Chinese collaborations. METHODS: Within this project, we first mapped relevant policies on PM in both the EU and China, and then we involved European and Chinese experts in PM in workshops and Delphi surveys in order to identify relevant priorities for the implementation of PM in sustainable healthcare. RESULTS: As a result of this process, we identified nine overarching priorities, each addressing specific aspects of the sustainability of healthcare systems and PM implementation, with the main goal of supporting policymakers in integrating PM approaches in the EU and China. DISCUSSION/CONCLUSION: The implementation of PM in health systems is appealing in terms of improved accuracy in diagnostics, treatment, and prevention of disease, as well as reduction of the side effects resulting from inefficient use of drugs. Research, development, and implementation of needed techniques require time and resources that can slow the adoption of PM in healthcare systems. The nine priorities we identified address some of the most critical points, trying to lay the foundations for a comprehensive approach.

Clinical development of mRNA therapies against solid tumors.

The mRNA-based therapeutics have become the hot spot of biopharmaceutical industries in recent years. The landscape of this area is expanding from infectious disease to cancer, which needs to be summarized to provide data supports for industries and research institutions. Based on the Trialtrove database, a total of 108 clinical trials from 1999 to 2021 were retrospectively analyzed. We have demonstrated that the clinical development of mRNA therapies against solid tumors is still at an early stage. There are evolutions in delivery systems from the dendritic cell to the lipid-based platform and in encoding strategies from the fixed tumor antigens to the personalized neoantigens. The adjuvant or maintenance therapy and the combination treatment with checkpoint inhibitors are becoming the major clinical development orientation.

Integrating China in the international consortium for personalised medicine. a position paper on healthcare professionals' education and citizens' empowerment in personalised medicine.

BACKGROUND: Personalised medicine (PM) has been fostered by technological and medical advances, but all stakeholders, including healthcare professionals, citizens and policy makers, should achieve adequate health literacy to promote PM implementation. The "Integrating China in the International Consortium for Personalised Medicine" (IC2PerMed) project, funded by the International Consortium for Personalised Medicine, focuses on this issue by highlighting the need to educate healthcare professionals and empower citizens. Within the aforementioned project, building on a mapping of European and Chinese policies in PM, experts in the field of PM participated in an online workshop and a following two-round Delphi survey, in order to identify the priority areas of intervention for healthcare professionals' education and curricula, engagement and empowerment of citizens and patients. RESULTS: Nine experts completed the survey and reached a consensus on seventeen priorities: seven were related to health professionals' education and curricula, whereas ten on citizen and patients' awareness and empowerment. CONCLUSION: These priorities emphasized the importance of education and health literacy, multidisciplinary and international collaboration, public trust, and consideration of ethical, legal, and social issues. The present experience highlights the relevance of the involvement of stakeholders in informing decision-makers, developing appropriate national plans, strategies, and policies, and ensuring the adequate implementation of PM in health systems.

Medical expenditure for lung cancer in China: a multicenter, hospital-based retrospective survey.

BACKGROUND: Lung cancer is the most prevalent cancer, and the leading cause of cancer-related deaths in China. The aim of this study was to estimate the direct medical expenditure incurred for lung cancer care and analyze the trend therein for the period 2002-2011 using nationally representative data in China METHODS: This study was based on 10-year, multicenter retrospective expenditure data collected from hospital records, covering 15,437 lung cancer patients from 13 provinces diagnosed during the period 2002-2011. All expenditure data were adjusted to 2011 to eliminate the effects of inflation using China's annual consumer price index. RESULTS: The direct medical expenditure for lung cancer care (in 2011) was 39,015 CNY (US$6,041) per case, with an annual growth rate of 7.55% from 2002 to 2011. Drug costs were the highest proportionally in the total medical expenditure (54.27%), followed by treatment expenditure (14.32%) and surgical expenditure (8.10%). Medical expenditures for the disease varied based on region, hospital level, type, and stage. CONCLUSION: The medical expenditure for lung cancer care is substantial in China. Drug costs and laboratory test are the main factors increasing medical costs.

Platform study of genotyping-guided precision medicine for rare solid tumours: a study protocol for a phase II, non-randomised, 18-month, open-label, multiarm, single-centre clinical trial testing the safety and efficacy of multiple Chinese-approved targeted drugs and PD-1 inhibitors in the treatment of metastatic rare tumours.

INTRODUCTION: Limited clinical studies have been conducted on rare solid tumours, and there are few guidelines on the diagnosis and treatment, including experiences with targeted therapy and immunotherapy, of rare solid tumours in China, resulting in limited treatment options and poor outcomes. This study first proposes a definition of rare tumours and is designed to test the preliminary efficacy of targeted and immunotherapy drugs for the treatment of rare tumours. METHODS AND ANALYSIS: This is a phase II, open-label, non-randomised, multiarm, single-centre clinical trial in patients with advanced rare solid tumours who failed standard treatment; the study aims to evaluate the safety and efficacy of targeted drugs in patients with advanced rare solid tumours with corresponding actionable alterations, as well as the safety and efficacy of immune checkpoint (programmed death receptor inhibitor 1, PD-1) inhibitors in patients with advanced rare solid tumours without actionable alterations. Patients with advanced rare tumours who fail standardised treatment and carry actionable alterations (Epidermal growth factor receptor (EGFR) mutations, ALK gene fusions, ROS-1 gene fusions, C-MET gene amplifications/mutations, BRAF mutations, CDKN2A mutations, BRCA1/2 mutations, HER-2 mutations/overexpressions/amplifications or C-KIT mutations) will be enrolled in the targeted therapy arm and be given the corresponding targeted drugs. Patients without actionable alterations will be enrolled in the PD-1 inhibitor arm and be treated with sintilimab. After the patients treated with vemurafenib, niraparib and palbociclib acquire resistance, they will receive combination treatment with sintilimab or atezolizumab. With the use of Simon's two-stage Minimax design, and the sample size was estimated to be 770. The primary endpoint of this study is the objective response rate. The secondary endpoints are progression-free survival in the targeted treatment group and single-agent immunotherapy group; the duration of response in the targeted therapy and single-agent immunotherapy groups; durable clinical benefit in the single-agent immunotherapy group; and the incidence of adverse events. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Chinese Academy of Medical Sciences (ID: 20/132-2328). The results from this study will be actively disseminated through manuscript publications and conference presentations. TRIAL REGISTRATION NUMBERS: NCT04423185; ChiCTR2000039310.

Health-related quality of life of patients with colorectal neoplasms in China: A multicenter cross-sectional survey.

BACKGROUND AND AIM: This study aimed to clarify health-related quality of life (HRQoL) of patients with colorectal precancer and colorectal cancer (CRC) in China and to better understand related utility scores. METHODS: A hospital-based cross-sectional survey was conducted in precancer and CRC patients from 2012 to 2014, covering 12 provinces in China. HRQoL was assessed with EuroQol 5-Dimensions 3-Levels. Utility scores were derived using Chinese value set. A multivariate regression model was established to explore potential predictors of utility scores. RESULTS: A total of 376 precancer (mean age 58.7 years, 61.2% men) and 2470 CRC patients (mean age 58.6 years, 57.6% men) were included. In five dimensions, there was a certain percentage of problem reported among precancer (range: 12.0% to 36.7%) and CRC (range: 32.4% to 50.3%) patients, with pain/discomfort being the most serious dimension. Utility scores of precancer and CRC patients were 0.870 (95% confidence interval [CI], 0.855-0.886) and 0.751 (95% CI, 0.742-0.759), both of which were lower than those of general Chinese population (0.960 [95% CI, 0.960-0.960]). Utilities for patients at stage I to stage IV were 0.742 (95% CI, 0.715-0.769), 0.722 (95% CI, 0.705-0.740), 0.756 (95% CI, 0.741-0.772), and 0.745 (95% CI, 0.742-0.767), respectively. Multivariate analysis showed that therapeutic regimen, time point of the interview, education, occupation, annual household income, and geographic region were associated with utilities of CRC patients. CONCLUSION: Health-related quality of life of both precancer and CRC patients in China declined considerably. Utility scores differed by sociodemographic and clinical characteristics, and findings of these utilities may facilitate implementation of further cost-utility evaluations.

Pharmacoeconomic Evaluation of Cancer Biosimilars Worldwide: A Systematic Review.

Background and Purpose: The availability of oncology biosimilars is deemed as a fundamental strategy to achieve sustainable health care. However, there is scarce systematic evidence on economic effectiveness of cancer biosimilars. We aimed to synthesize evidence from pharmacoeconomic evaluation of oncology biosimilars globally, provide essential data and methodological reference for involved stakeholders. Materials and Methods: This systematic review was conducted in PubMed, embase, the Cochrane library, CRD, ISPOR and NICE utill December 31, 2019. Information on basic characteristics, evaluation methodology and results were extracted. Quality of included studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards Checklist. Results: For 17 studies identified (13 from Europe and four from United States), the overall quality was generally acceptable. A total of seven biological molecules involved with filgrastim, EPOETIN α, and trastuzumab leading the three. The mostly common evaluation perspective was payer, but the time horizon varied greatly. There were ten studies which adopted cost minimization analysis to evaluate efficiency while seven studies adopted budget impact analysis to address affordability, with cost ratio and cost saving being its corresponding primary endpoint. Although the comparability of included studies was limited and specific results were largely affected by uptake and price discount rates of the oncology biosimilar, the comprehensive results consistently favored its promotion. Conclusion: Globally, the economic evaluation of cancer biosimilars is in its initial phase. However, limited evidence from developed countries consistently supported both cost-effectiveness of efficiency and affordability of oncology biosimilars, while they were largely affected by uptake and price discount rate.

Economic burden of lung cancer attributable to smoking in China in 2015.

BACKGROUND: Lung cancer is substantially attributable to smoking, but detailed related estimates on smoking-attributable expenditure (SAE) in China are not available yet, which could inform tobacco control and cancer prevention initiatives. METHODS: A prevalence-based approach was adopted to estimate the total SAE, including direct expenditure (medical and non-medical) and indirect cost (disability and premature death). Detailed per-patient data on direct expenditure and work-loss days were acquired from a unique multicentre survey in China. Other parameters were from literatures and official reports. RESULTS: The total estimated SAE of lung cancer was US$5249 million in China in 2015 (0.05 % of gross domestic product for China). The estimated direct SAE was US$1937 million (36.9 % of the total SAE), accounting for 0.29 % of total healthcare expenditure for China. The medical and non-medical direct expenditures were US$1749 million and US$188 million, respectively. The estimated indirect cost was US$3312 million (63.1 % of the total SAE), including US$377 million due to disability and US$2935 million due to premature death. The SAE increased with age, peaking at 60-64 years (US$1004 million), and was higher among men, in urban areas and in eastern China. If smoking prevalence was reduced to 20%, as is the goal of Healthy China 2030, the total SAE would be decreased by 4.9 %. CONCLUSIONS: Smoking-attributable economic burden caused by lung cancer was substantial in China in 2015, and will continue increasing given current trends in lung cancer. However, future economic burden can be prevented with implementation of effective tobacco control and other interventions.

Changes in clinical trials of cancer drugs in mainland China over the decade 2009-18: a systematic review.

As a result of recent, substantial capacity building, a new landscape for cancer drug trials is emerging in China. However, data on the characteristics of cancer drug trials, and how they have changed over time, are scarce. Based on clinical trials published on the China Food and Drug Administration Registration and Information Disclosure Platform for Drug Clinical Studies, we aimed to systematically review changes over time in clinical trials of cancer drugs in mainland China from 2009 to 2018, to provide insight on the effectiveness of the pharmaceutical industry and identify unmet clinical needs of stakeholders. A total of 1493 trials of 751 newly tested cancer drugs were initiated. Increases over time were observed for the annual number of initiated trials, newly tested drugs, and newly added leading clinical trial units, with a sharp increase after 2016. Of the 1385 trials in which cancer types were identified, solid tumours (325 [23%] trials), non-small-cell lung cancer (232 [17%]), and lymphoma (126 [9%]) were the most common. A markedly uneven distribution was also observed in the geography of leading units with the largest number of leading units located in east China (50 [41%]) and the smallest number located in southwest China (4 [3%]). The growth trends we observed illustrate the progress in and increasing capability of cancer drug research and development achieved in mainland China over the decade from 2009. The low number of clinical trials on tumours with epidemiological characteristics unique to the Chinese population and the unbalanced geographical distribution of leading clinical trial units will provide potential targets for policy makers and other stakeholders. Further research efforts should address cancers uniquely relevant to Chinese populations, globally rare cancers, and the balance between equitable drug access, efficiency, and sustainability of cancer drug research and development in mainland China.

Short-term impact of breast cancer screening intervention on health-related quality of life in China: A multicentre cross-sectional survey.

OBJECTIVE: The impact of participating in breast cancer screening programmes on health-related quality of life (HRQoL)is poorly understood. METHODS: Based on a national breast cancer screening programme in China, a multicentre cross-sectional survey was conducted covering 12 provinces from September 2013 to December 2014. HRQoL of participants in the screening population and general population was evaluated by the three-levelEuroQol-five-Dimensions (EQ-5D-3L) instrument, and utility scores were generated through the Chinese value set. Univariate and multivariate regression analyses were performed to explore determinants of utility scores and anxiety/depression problems. RESULTS: For screening group and general population (n = 4756, mean age = 51.6 year old), the corresponding utility scores were 0.937 (95% CI, 0.933-0.941) and 0.953 (0.949-0.957) (P < .001). Pain/discomfort and anxiety/depression were the most common reported in both groups (51.4% and 34.3%, P < .001). Utility scores at prescreening, in-screening, and postscreening interview timings were 0.928 (0.921-0.935), 0.958 (0.948-0.969), and 0.938 (0.933-0.943), respectively (P < .001); the corresponding proportions of anxiety/depression reporting were 25.9%, 16.3%, and 21.1%, respectively (P = .004). Interview timing, geographical region, and insurance status were associated with HRQoL and anxiety/depression in women at high-risk of breast cancer. CONCLUSIONS: Utility scores of screening participants were significantly lower than that of general population in China, but the difference may be clinically insignificant. Further cohort studies using HRQoL measurements are needed.

Clinical characteristics and medical service utilization of lung cancer in China, 2005-2014: Overall design and results from a multicenter retrospective epidemiologic survey.

OBJECTIVES: This study aimed to explore the clinical profile and its trajectory of lung cancer on clinicopathological characteristics and medical service utilization in China. METHODS: Patients diagnosed with primary lung cancer in tertiary hospitals during 2005-14 were selected from seven geographic regions of China. Data on clinical characteristics and medical service utilization was extracted from medical record, and the ten-year trends were explored. RESULTS: A total of 7184 patients were included, the mean age was 58.3 years and the male-to-female-ratio was 2.7. From 2005 to 2014, the proportion of ≥60 year-old patients increased from 41.2% to 56.2% (p < 0.001). The smoking rate decreased from 62.9% to 51.1% (p < 0.001) and the proportion of females increased from 23.5% to 31.9% (p < 0.001). The proportion of advanced stage increased from 41.9% to 47.4% (p < 0.001). Adenocarcinoma's proportion increased from 36.4% to 53.5% (p < 0.001) while that of squamous carcinoma decreased from 45.4% to 34.4% (p < 0.001). The application of chest X-ray dropped from 50.2% to 31.0% (p < 0.001) but that of chest CT increased from 65.8% to 81.4% (p < 0.001). As two main treatment options, chemotherapy (p = 0.290) and surgery (p = 0.497) remained stable. The medical expenditure per patient increased from 40,508 to 66,020 Chinese Yuan (p < 0.001). CONCLUSIONS: The sustaining high smoking exposure, increasing proportion of female patients, advancing clinical stage, shifting of predominant pathology and increasing medical expenditure demonstrate potential challenges and directions on lung cancer prevention and control in China. Despite substantial changes of clinical characteristics, main treatment options remained unchanged, which needs further investigation.

Medical expenses of urban Chinese patients with stomach cancer during 2002-2011: a hospital-based multicenter retrospective study.

BACKGROUND: In China, stomach cancer is the third most common cancer and the third leading cause of cancer death. Few studies have examined Chinese stomach cancer patients' medical expenses and their associated trends. The Cancer Screening Program in Urban China (CanSPUC) is a Major Public Health Project funded by the central government. Through this project, we have extracted patients' medical expenses from hospital billing data to examine the costs of the first course treatments (which refers to 2 months before and 10 months after the date of cancer diagnosis) in Chinese patients with stomach cancer and the associated trends. METHODS: The expense data of 14,692 urban Chinese patients with stomach cancer were collected from 40 hospitals in 13 provinces. We estimated the inflation-adjusted medical expenses per patient during 2002-2011. We described the time trends of medical expenses at the country-level, and those trends by subgroup, and analyzed the compositions of medical expenses. We constructed the Generalized Linear Mixed (GLM) regression model with Poisson distribution to examine the factors that were associated with medical expenses per patient. RESULTS: The average medical expenses of the first course treatments were about 43,249 CNY (6851 USD) in 2011, more than twice of that in 2002. The expenses increased by an average annual rate of 7.4%. Longer stay during hospitalization and an increased number of episodes of care are the two main contributors to the expense increase. The upward trend of medical expenses was observed in almost all patient subgroups. Drug expenses accounted for over half of the medical expenses. CONCLUSIONS: The average medical expenses of the first course (2 months before and 10 months after the date of cancer diagnosis) treatments per stomach cancer patient in urban China in 2011 were doubled during the previous 10 years, and about twice as high as the per capita disposable income of urban households in the same year. Such high expenses indicate that it makes economic sense to invest in cancer prevention and control in China.

International trends in lung cancer incidence from 1973 to 2007.

Lung cancer is the commonly diagnosed cancer and one of the most important avoidable causes of death around the world. We conducted the study to investigate the pattern of lung cancer incidence worldwide. Joinpoint analysis was used to extend international lung cancer incidence rates by the latest data from Cancer Incidence in Five Continents over the 35-year period 1973-2007 from 24 populations from Americas, Asia, Europe, and Oceania. Age-standardized incidence rates (ASRs) of lung cancer were from 33.3 to 66.8 per 100,000 among males and 10.5 to 37.4 per 100,000 among females in most of Americas, Europe, and Oceania populations during the period 2003-2007. In Asia, ASRs in China (Hong Kong) were the highest, up to 53.3 per 100,000 in males and 21.9 per 100,000 in females during the period 2003-2007. The international trends between 1973 and 2007 showed that ASRs of lung cancer among males were declining in 13 of 18 selected Americas, Oceania, and Europe populations, with AAPC from -0.7% to -2.9%, whereas the rates among females in 18 selected populations were increasing, with AAPC from 1.3% to 5.0%. The increasing and decreasing trends of ASRs of lung cancer in Asia have a geographic variation but no gender differences. Although the decreasing trends in ASRs of lung cancer for males were observed, the ASRs were higher than females. The declining trends in males were mainly attributed to tobacco control, whereas the increasing trends in females should be given more concern and need to be further studied in etiology factors.

Medical expenditure for liver cancer in urban China: A 10-year multicenter retrospective survey (2002-2011).

OBJECTIVE: This study aims to understand the medical expenditure for liver cancer during 2002-2011 in urban areas of China. MATERIALS AND METHODS: This is a retrospective study. Based on a stratified cluster sampling method, a medical expenditure survey collected basic personal information from related medical records. Two-tailed independent sample t-test, variance analysis, and Student-Newman-Keuls Tests were used in cost analysis for the corresponding data types. RESULTS: A total of 12,342 liver cancer patients were included in the analysis. Overall average medical expenditure per case for liver cancer diagnosis and treatment in China has increased from ¥21, 950 to ¥40, 386 over the study period. For each liver cancer patient diagnosed between 2009 and 2011, the average expenditures were 29,332 CNY for stage I, 35,754 CNY for stage II, 34,288 CNY for stage III, and 30,275 CNY for stage IV diseases (P < 0.001). Pharmaceuticals accounted for the biggest part of the medical expenditure and it rose from 48.01% to 52.96% during these ten years, and the share of nursing fee expenses was the lowest (around 1%). Over the entire 10-year data period, the per capita expenditure of the east region (32,983 CNY) was higher than that of the west region (26,219 CNY) and slightly higher than the central region (31,018 CNY, P < 0.001). DISCUSSION: As a major cancer in China, liver cancer accounts for a large portion of health economic burden and its medical expenditure is heavy for families. Early diagnosis and treatment for liver cancer will save medical expenditure. CONCLUSION: The economic burden of liver cancer is high in China and related medical expenditure has increased.

Health-related quality of life and utility scores of patients with breast neoplasms in China: A multicenter cross-sectional survey.

BACKGROUND: Health-related quality of life and utility scores of patients with breast cancer and precancerous lesions are sparse in China. This study aimed to derive utility scores of patients with breast cancer and precancer in China. MATERIAL AND METHODS: An interviewer-administered cross-sectional survey was conducted in 12 provinces across China from 2013 to 2014. The three-level EuroQol-5-Dimension instrument was used to evaluate quality of life, and utility scores were generated using the Chinese value set. Univariate and multivariate analyses were performed to explore the determinants of utility scores. RESULTS: In total, 2626 breast cancer and 471 precancer patients were included. Mean age was 49.1 for breast cancer and 41.4 years for precancer (p < 0.001). Among the five dimensions, pain/discomfort was the most reported problem, 53.9% in breast cancer and 29.3% in precancer patients. Mean (95% CI) utility scores for breast cancer and precancer patients were estimated as 0.887 (0.875-0.899) and 0.781 (0.774-0.788), and the scores of breast cancer at stage-I, stage-II, stage-III and stage-IV were 0.789 (0.774-0.805), 0.793 (0.783-0.802), 0.774 (0.759-0.788) and 0.686 (0.654-0.717), respectively. Mean (95% CI) visual analogue scale scores for breast cancer and precancer were 75.6 (74.0-77.3) and 72.8 (72.3-73.3). Multiple regression showed advanced clinical stage, lower educational level, lower household income, surgery treatment, and undergoing treatment were independently associated with lower utility scores for breast cancer patients. CONCLUSION: The utility scores deteriorate with the severity of breast neoplasms. Detailed utility scores of breast cancer and precancer are fundamental for further cost-utility analysis in China.

Medical and non-medical expenditure for breast cancer diagnosis and treatment in China: a multicenter cross-sectional study.

AIM: We aimed to assess economic burden of breast cancer (BC) diagnosis and treatment in China through a multicenter cross-sectional study, and to obtain theoretical evidence for policy-making. METHODS: This survey was conducted in 37 hospital centers across 13 provinces in China from September 2012 to December 2014. We collected information on the subject characteristics. We then assessed the medical and non-medical expenditure for BC diagnosis and treatment, factors influencing the average case expense, variations between medical and non-medical expenditure at different clinical stages, economic impact of overall expenditure in newly diagnosed course after reimbursement to the patient's family, composition of non-medical expenditure and time loss for the patient and family. RESULTS: Among 2746 women with BC (72.6% were admitted to specialized hospitals), the overall average expenditure was US $8450 (medical expenditure: $7527; non-medical expenditure: $922). Significant differences were found among the overall expenditure in the four clinical stages (P < 0.0001); the expenditure was higher in stages III and IV than that in stages I and II, whereas the stage IV was the highest (P < 0.0001). Moreover, a higher self-reported predicted reimbursement ratio was associated with a less economic impact on the patient's family, and the average time lost was estimated as $1529. CONCLUSIONS: Early detection and treatment of breast cancer might be effective for decreasing the economic burden, because costs escalate as the degree of malignancy increases.

Medical expenditure for esophageal cancer in China: a 10-year multicenter retrospective survey (2002-2011).

BACKGROUND: Esophageal cancer is associated with substantial disease burden in China, and data on the economic burden are fundamental for setting priorities in cancer interventions. The medical expenditure for the diagnosis and treatment of esophageal cancer in China has not been fully quantified. This study aimed to examine the medical expenditure of Chinese patients with esophageal cancer and the associated trends. METHODS: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 37 hospitals in 13 provinces/municipalities across China as a part of the Cancer Screening Program of Urban China. For each esophageal cancer patient diagnosed between 2002 and 2011, clinical information and expense data were extracted by using structured questionnaires. All expense data were reported in Chinese Yuan (CNY; 1 CNY = 0.155 USD) based on the 2011 value and inflated using the year-specific health care consumer price index for China. RESULTS: A total of 14,967 esophageal cancer patients were included in the analysis. It was estimated that the overall average expenditure per patient was 38,666 CNY, and an average annual increase of 6.27% was observed from 2002 (25,111 CNY) to 2011 (46,124 CNY). The average expenditures were 34,460 CNY for stage I, 39,302 CNY for stage II, 40,353 CNY for stage III, and 37,432 CNY for stage IV diseases (P < 0.01). The expenditure also differed by the therapy type, which was 38,492 CNY for surgery, 27,933 CNY for radiotherapy, and 27,805 CNY for chemotherapy (P < 0.05). Drugs contributed to 45.02% of the overall expenditure. CONCLUSIONS: These conservative estimates suggested that medical expenditures for esophageal cancer in China substantially increased in the last 10 years, treatment for early-stage esophageal cancer costs less than that for advanced cases, and spending on drugs continued to account for a considerable proportion of the overall expenditure.
